FIELD: agricultural engineering.

SUBSTANCE: soil-cultivating roller is a hollow cylinder equipped with axle (1) with ribs (2) evenly spaced around the circumference connecting vertical discs (3). Perforated trays 3 are installed between adjacent ribs 1 with their convex part outward. Ribs 1 are made in the form of wedge-shaped strips, the pointed part of which is directed outward at an acute angle to the tangent to the circumference of vertical disks 2.
